I think the answer has to be an unequivocal "yes". If you're not OGE then by definition you must be IGE. And if you enter vortex ring while you're IGE, for sure it won't last long. With any luck the worst damage will be a couple of bent skids, though I guess a rollover is more likely. But anyway it won't have lasted long.
Unless of course you use the Vuichard technique, which guarantees a quick and safe recovery. (Oops, sorry, it just slipped out. Just kidding, guys).
